To all whom it may concern.-

Be it known that I, Gnonen ScHUBEnr, a citizen of the United States,residing at alnut, in the county of Bosque and State of Texas, haveinvented a new and useful Grain- Binder, of which the following is aspecification.

This invention relates to improvements in a grain-binder of a kind knownas a platform-binder, in which the cord-carrying arm orneedleandneedle-operating mechanism are placed below the upper deck of theplatform, and the cord-tying mechanism is placed above the upper deck ofthe platform.

The objects of my improvements are, first, to construct a needle insections, and to construct mechanism to curve said needle in position toa proper curvature to conform to the sheaf to be bound at the beginningof the binding operation, and to again straighten out said needle at theend of the binding operation, so as to pass beneath the upper deck ofthe platform, so that the grain can be shifted direct from thegrain-receiving platform on the needle by a suitable conveyer inventedby myself and patented February 17,1891, No. MGATS, thus dispensing withall packing and elevating and receiving mechanism, thus promotingsimplicity and cheapness of the construction of such grainbinders;second, to construct a simple, light, and durable clutching mechanism toconnect and disconnect the binding mechanism with the harvester orconveyor gearing; third, to construct a simple gear-shifting mechanismto impart reciprocating movement to the conveyer, and, fourth, toconstruct a light and simple locking mechanism to lock the gearshiftingmechanism in position after being shifted to the desired position. iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a plan view of a harvester-platformprovided with my improvements. The upper front plate of the platform andthe breast-board are removed to show parts below. Fig.2 is a frontelevation viewof Fig. 1.

9 is a spring secured to the binder-frame in position to engage with itsfree end with the sprockets of the wheel 9 as shown in Figs. 2 and 5.

The operations may be summarized as follows, viz: The shaft 75 receivesits rotation from mechanism of the harvester (not shown in the drawings)and is rotated in the direction as shown by arrow in Fig. 1. When theoperator desires to start the conveyer, he draws the draw-rod Sstubbleward, thus drawing the incline guide it in the same direction andengaging the bevel-pinion j with the bevel-pinion K and starting theconveyor on its stubbleward movement, and as the conveyer movesstubbleward the projection 75' moves against the rearward-projecting endof the rod n, moving it along stubbleward, thereby compressing thespring n and shifting the rod m in the same direction, when the stubbleend of said rod m will ascend on the inclined block 71 thereby elevatingthe stubble end of the rod on and causing it to elevate the rear end ofthe lever L, thus disengaging said lever L from the shoulder L when saidlever is moved in the position, as seen in dotted lines in Fig. 1, bythe springn', when said lever L will drop over the shoulder L and thusis locked in position. As the rear end of the lever L is movedstubbleward the rod K is drawn in the opposite direction, therebydisengaging the bevel-pinion 7' from bevel-pinion K and engaging it withthe bevel-pinion K thus reversing the movement of the conveyer. As theconveyer nears the stubble end of its movement the beveled end 75 of theblockt engages beneath the free end of the needle and elevates the sameto the extent as shown in Fig. 5, drawing the connecting-rod 7F, andthereby imparting a slight rotation to the shafts g and e, and movingthe bell-crank g connecting-rod g and sprocket-wheel g in the positionas seen in Fig. 5, and moving the arm f past the extension f allowingthe arm f to descend and hold the grain untilgrasped by the needle. Theslight forward movement of the shaft 9 moves the arm g off the clutch Jallowing the spring J to move the sprocket-wheel J 6 outward or forwardin line with the sprocket-wheel g causing the clutch J to engage withthe pin J The spring 9 prevents the gearing from having any rearwardmovement, and as the rotation of the shaft J is reversed the clutch Jwill be operated by the pin J and cause the sprocketwheel g to completeone revolution, when the arm g will again engage with the clutch J andforce the sprocket-wheel J 6 to the rear and disengage the clutch J fromthe pin J when the binding mechanism will remain at rest in the positionas seen in Fig. 2 with the arm f in contact with the extensionf, holdingthe armf at an elevation, as seen in Fig. 2, until again started, asheretofore described. As the binding mechanism is operated by thesprocket-wheel J 6 the section h is first moved upward by the arm h andconnecting-rod 72 to the curvature, as shown in Fig. 4, when the curvedend of the connecting-rod 7t will come in contact with the rear end ofthe section h and prevent said section from having any further inwardmovement. At this time the forward end 2' of the connecting-rod 7t willpass from under the bracket 2' and ascend through the notch i in theplate A bypressure of the arm its on the connecting-rod h the section his caused to elevate, and as the free end of the section h begins toelevate the spring i is released and engages with the stud 1) and locksthe section h and connecting-rod 72- in position, when the needle is inposition to be moved upward, as shown in dotted lines in Fig. 4:, tocompress the gavel and deliver the cord to the knot-tying mechanism.(Not shown in the drawings.) As the section 7L nears the end of itsreturn movement the spring i comes in contact with the post i and ispressed against the section h, and thus disengages the projection i,when the end i will be in position to again engage beneath the bracket2' and compel the section 71' to unfold grainward to the position asseen in dotted lines in Fig. 2. As the conveyer nears the end of itsgrainward movement the projection t comes in contact with the rearwardprojecting end of the rod m and draws said rod m grainward, the dog ofshifting along on the smooth surface of the block n with its IIO freeend projecting grainward until it comes in contact with the shoulder atprojection 12*, when it will be drawn over and elevate the stubble endof the rod m and the rear end of the lever L, and disengaging said leverL from the shoulder L the near end of said lever L will now be movedgrainward by reason of the dog n or eye of the rod 111. resting againstthe lug L and thus disengaging the bevelpinion 7' from the bevel-pinionK and allowing the conveyer to remain at rest until again started by theoperator, as heretofore dea projecting stubbleward and a short distancestubbleward from the shoulder L as seen in Figs. 1 and 9, and with itsstubble end formed inclined and extending a short distance past theopening L J designates a shaft extending through the strip a near thestubble end of the platform and journaled with its rear end in the sill6L2 and with its front end in the bearing J The front end or peripheryof the pivoted bearing J is machined and journaled in therearward-projecting iiange J of the bearing J*, as shown in the dottedlines in Fig. 1, and having its rear end supported on the shaft J.

The operations may be summarized as follows, viz: The shaft receives itsrotation from mechanism of the harvester (not shown in the drawings) andis rotated in the direction as shown by arrow in Fig. 1. When theoperator desires to start the conveyer, he draws the draw-rod Sstubbleward, thus drawing the incline guide it in the same direction andengaging the bevel-pinion j with the bevel-pinion K and starting theconveyer on its stubbleward movement, and as the conveyer movesstubbleward the projection 6 moves against the rearward-projecting endof the rod 71, moving it along stubbleward, thereby compressing thespring 72' and shifting the rod on in the same direction, when thestubble end of said rod m will ascend on the inclined block 71?, therebyelevating the stubble end of the rod m and causing it to elevate therear end of the lever L, thus disengaging said lever L from the shoulderL when said lever is moved in the position, as seen in dotted lines inFig. 1, by the spring n, when said lever L will drop over the shoulder Land thus is locked in position. As the rear end of the lever L is movedstubbleward the rod K is drawn in the opposite direction, therebydisengaging the bevel-pinion j from bevel-pinion K and engaging it withthe bevel-pinion K thus reversing the movement of the conveycr. As theconveycr nears the stubble end of its movement the beveled end 15 of theblock if engages beneath the free end of the needle and elevates thesame to the extentas shown in Fig. 5, drawing the connecting-rod 7V, andthereby imparting a slight rotation to the shafts g and e, and movingthe bell-crank g connecting-rod g and sprocket-wheel g in the positionas seen in Fig. 5, and moving the arm f past the extension f allowingthe arm f to descend and hold the grain untilgrasped by the needle. Theslight forward movement of the shaft g moves the arm g ofi the clutch Jallowing the spring J to move the sprocket-wheel J 6 outward or forwardin line with the sprocket-wheel g causing the clutch J to engage withthe pin J The spring g prevents the gearing from having any rearwardmovement, and as the rotation of the shaft J is reversed the clutch Jwill be operated by the pin J and cause the sprocketwheel g to completeone revolution, when the arm g will again engage with the clutch J andforce the sprocket-wheel J 6 to the rear and disengage the clutch J fromthe pin J when the binding mechanism will remain at rest in the positionas seen in Fig. 2 with the arm f in contact with the extension f holdingthe armf at an elevation, as seen in Fig. 2, until again started, asheretofore described. As the binding mechanism is operated by thesprocket-wheel J 6 the section h is first moved upward by the arm 77.and connecting-rod 71 to the curvature, as shown in Fig. 4, when thecurved end of the connecting-rod 71. will come in contact with the rearend of the section h and prevent said section from having any furtherinward movement. At this time the forward end i of the connecting-rod hwill pass from under the bracket 01 and ascend through the notch i inthe plate A bypressure of the arm h on the connecting-rod 7t the sectionh is caused to elevate, and as the free end of the section h begins toelevate the spring 2' is released and engages with the stud i and locksthe section it and connecting-rod 7% in position, when the needle is inposition to be moved upward, as shown in dotted lines in Fig. 4, tocompress the gavel and deliver the cord to the knot-tying mechanism.(Not shown in the drawings.) As the section h nears the end of itsreturn movement the spring 1' comes in contact with the post 2' and ispressed against the section it, and thus disengages the projection '5,when the end 2' will be in position to again engage beneath the bracketi and compel the section 71 to unfold grainward to the position as seenin dotted lines in Fig. 2. As the conveycr nears the end of itsgrainward movement the projection t comes in contact with the rearwardprojecting end of the rod 117. and draws said rod m grainward, the dog01. shifting along on the smooth surface of the block 71 with its freeend projecting grainward until it comes in contact with the shoulder atprojection 77;, when it will be drawn over and elevate the stubble endof the rod on and the rear end of the lever L, and disengaging saidlever L from the shoulder L the near end of said lever L will now bemoved grainward by reason of the dog 71, or eye of the rod m restingagainst the lug L and thus disengaging the bevelpinion 7' from thebevel-pinion K and allowing the conveyer to remain at rest until againstarted by the operator, as heretofore described. The spring a is coiledclose enough on the rod m so as to be entirely compressed at the timethe lever L is disengaged from the shoulder L to allow the conveyer toact direct on the lever L and the gear-shifting mechanism to disengagethe gearing if the spring a should fail to do so.

It will be understood that I do not wish to limit myself to the preciseproportions and details of construction herein described, as I am awarethat many modifications mav be made therein without departing from thespirit of my invention.
